Looks like a yucca. Here in Texas they are called cow killers. The tips of the leaves have a hard sharp point. They will also have, in a few years, a tall flower spike with a bunch of cream colored flowers. You really don't want these things in your landscape if you have pets or children. The best way to kill them is to chop them at ground level and pour diesel fuel on them.
I don't know if diesel works on poison ivy or not but GreenLight Cut Vine and Stump Killer sure does. If you mix diesel and molasses 50/50 and pour it over the cut yucca it helps tremendously in the after effects of the diesel. Ranchers in South Texas use the mixture to get rid of the yucca and mesquite thickets without long term harm to the grasses. The molasses make the soil microbes multiply and they eat the diesel residue left in the soil.Diesel!? Guess I may as well napalm the whole yard since I'm fighting poison ivy as well.
I'm fully aware you should not burn poison ivy, I don't have a death wish.
There are different types or varieties. I know what you have because I have a bunch of them, just like yours, scattered around my property. Yours is very young. It is a type that does not have a trunk. There are different names. Spanish dagger is one, Aloe dagger another, Spanish Yucca another. In about 5 - 10 years it will send up a long spike and produce flowers. It may or may not have a trunk. Some of mine do and some don't but they look identical otherwise.Hmm, looking online I'm not convinced it's yucca. Anything else you know of that looks similar?
Looks like young yucca still has a bit of a trunk. This looked to have no trunk.
Nope, vinegar won't work. I use diesel and molasses because it doesn't last in the soil as long as chemicals like triclopyr does. I wouldn't use diesel in my vegetable garden but out in the landscape and fence lines it is the safest, cheapest and most effective killer for these types of plants and unwanted brush and trees.If it is Yucca, i wonder if vinegar would work to kill them? I sure wouldn't want to pour diesel fuel on my soil.
Vinegar DOES NOT WORK on poison ivy. It's root system is too large. Roundup will work but only after many applications. What does kill poison ivy is GreenLight Cut Vine and Stump Killer
I've looked for that stuff, but i can't seem to find any. I do have the Roundup poison ivy killer, not the regular weed killer. And I have crossbow if I need to get really nasty.Vinegar DOES NOT WORK on poison ivy. It's root system is too large. Roundup will work but only after many applications.

Vinegar is not a systemic. It will kill the tops but not the roots. It will finally kill the plant but you still have to do it multiple times. Regular Roundup is a systemic as it is absorbed thru the leaves and into the roots but since poison ivy has such a robust root system it takes many applications. I have never used the Roundup Poison Ivy Killer so I have no information on that product. There are different brand names of stump and vine killer. Bonide is another popular brand. Home Depot, Lowes and WalMart all carry it. If you follow the directions you don't have to worry about damaging anything else. It is not a spray. You apply a few DROPS of this stuff onto the stump of what ever it is you want to kill.I've looked for that stuff, but i can't seem to find any.

I'm going to try the concentrate vinegar first as a ground clear. I'm going to clear out that whole bed of anything. It's over run with Ivy's and various grasses. Once I get rid of the lesser stuff I can Target the poison ivy a little stronger as needed. Hopefully I won't kill the trees in the process. There are some oak, magnolia, sago and other palms in there too.
About the only creosote available in the US is coal tar creosote. It is used for marine pilings, telephone poles etc. One can make creosote for roofing by mixing coal tar and diesel fuel 50/50. I would guess it would kill poison ivy but the cleanup of the coal tar would be onerous at best. Molasses mixed with diesel fuel is the only way to eliminate the hazards of diesel fuel. Coal tar removal is akin to stripping the roof off of a gravel roof building and then you have to have a hazardous waste disposal site to dump it. Medina Inc. of Hondo Tx has been cleaning up hazardous sites where the soil is contaminated for years and the main ingredient is molasses.
